RAIL-JOINT.

v SPECIFICATION forming part of Letters Patent No. 769,056, dated August 30, 1904.

I I Application filed February 2'7, 1904. Serial No. 195 ,568. (No model.)

To all whom it may concern:

Be it known that I, JERRY CAMPBELL, a citizen of the United States, residing at McNoel, in the county of'Massac and State of Illinois, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention embodiesa novel construction of scarf-joint for establishing an interlocking connection for the meeting ends of rails and the like.

The'essential object of the invention is to promote to a maximum degree the rigidity of the joint, to afford a continuous bearing at the point of jointure, and to provide a joint involving an extreme simplicity asregards the general structure thereof.

For a full description of the invention and the merits thereof and also to acquire a knowledge of' the-details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention'is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a railjoint embodying the invention. Fig. 2 is a horizontal sectional-view through the adjacent end portions =-of the rails. Fig. 3 is a vertical sectional view taken about on the line X X of Fig. 1. Fig. i is a vertical sectional view taken about on thelin'e Y Y of Fig. 1. Fig. 5 is a vertical sectional view taken about on the line Z Z of Fig. 1. Fig. 6 is a perspective view of one of the rail ends. Fig. 7 is a perspective view of the other rail end.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the rails 1 are, generally speaking, of the ordinary type in common use and consist of the head 2, the webs 3, and the base. 4. Since the rail ends are formed "so as to interlock tosecure the necessary rigidity of the joint, it is desirablethat same be made heavier, so as to facilitate the above. The rail ends are secured to-' may be slightly elongated to allow for the usual contraction and expansion of the rails .due to atmospheric conditions or the like. The head portions 2 of each of the adjacent rail ends are cut away longitudinally, as shown at 6, the extreme ends of the head portions 2 forming horizontal extensions 7. The cut-away portions of the rail ends, as shown at 6, when the joint is in operative position are on the same level and in their coincident positions afford acontinuous surface or hearing for the rolling-stock passing thereover. The web portions 3 of the rail ends adjacent the cut-away portions 6 are provided with lateral enlargements 8, and adjacent its enlargement 8 one of the rails is provided-with a lateral extension 9, which forms a part of the web 3 thereof. The rail which is provided with the lateral extension 9 adjacent the web portion thereof is designated 1*,and the upper side of the lateral extension 9, as well as the lateral enlargement 8 of this rail 1, is formed so as to provide a continuous groove 10. The

groove 10 receives the extension 7 and the adjacent cut-away portion 6 of the rail 1, these portions being undercut, as at 11, to effect a locking-joint to prevent any lateral play or movement of the rail ends. The upper side of the enlargement 8 of the rail 1 is likewise provided with a groove 12 to receive the extension 7 of the rail 1*, the last-mentioned extension being also undercut at 11, so as to cooperate to promote the general rigidity of the joint.

When the joint is in position, the cut-away portions 6 of the rail ends are adjacent each other and the groove 10 of the joint of the rail 1 is interlockingly engaged by the undercut portions 11 of the extension 7 of the rail 1. The extension 7 of the rail 1 is also receivedby the groove 12 of the rail 1.

Having thus described the invention, what is claimed as new is" In a rail-joint, the combination of rail ends having the head portions thereof cut away longitudinally to form a scarf-joint, lateral enthe rails being also grooved so as to interlock with the aforementioned lateral extension of the other rail, and securingbolts passed 5 through openings in the rail ends securing same together.

In testimony whereof I affix my signature in presence of two witnesses.
